I do not think I replaced the pulsator, unless it came with my autozone
pump. The CPI and nut kit where ACDelco parts.

I kind of think it might be the catlytic converter now. That is what a
couple people have told me and it seems like these symptoms could be
caused by a clogged converter. I will test it first since it is a bit
easier. Then I guess I will either do the test drive you suggested and
change the pulsator.

Thanks for the suggestions,

Dave
